And when it does, this modified SL 65 should race straight down a runway against an Enzo ....


Seriously though, how long do you think it will be before somebody figures out how to successfully and seriously enlarge the 65 engines? With fenders widened to house much wider tires (doesn't Michelin now make a 355/30 ZR-21 tire?) and an enlarged engine (let's say to 7.0 liters with upgraded turbo's to go with it, why not), and also somehow puts in a tranny that can withstand it ... and what will we have? Scary is a total understatement here ladies and gentlemen .....

We will then see these cars first have 800, then 900, then over 1000 horsepower with torque figures maybe 1,000 to 1,400 lb/ft, yes?

And does anyone think AMG might later (like within next 2 to 3 years) come out with an even more powerful engine than even the 65 engines? Like maybe 7.0 liter twin-turbo AMG V-12? With the all-new strengthened 7-speed trans?

Thanks for all the info guys .....

The guys at Brabus enlarged it to 6.3, pumpsuot 640hp and 1026nm

But you are talking about the v8 5.5 liters I'm right??

Nop, the V12

"The BRABUS E V12 of the model year 2004 is powered by the Brabus SV 12 Biturbo increased-displacement engine, which is implanted with almost surgical precision into the modified engine bay of the E-Class.

The displacement of the 12-cylinder biturbo engine, which normally resides in a current Mercedes S600 model, is increased from 5.5 to 6.3 liters. The increase is facilitated with the installation of a custom-designed one-piece crankshaft, larger diameter pistons, corresponding larger bore and precision-balanced piston rods. The BRABUS engine is further fitted with sport camshafts, precision-machined cylinder heads, a stainless-steel high-performance sport exhaust system with metal catalysts and four exhaust tips as well as newly programmed engine electronics.

With these modifications the engine of the BRABUS E V12 delivers a whopping 640 hp (471 kW) at 5,100 rpm and an even more impressive peak torque of 765 ft lbs (1026 Nm) available from just 1,750 rpm.

Thus equipped the new BRABUS E V12 delivers performance that places the sedan on a level with the world's fastest sports cars: 4.2 seconds for 0 to 100 km/h, 12.9 seconds for 0 to 200 km/h and an electronically limited top speed of 340 km/h are the performance cornerstones of this exclusive high-performance sedan."

Yes Brabus did enlarge the standard twin turbo 5.5 liter V-12 to 6.3 liters, but they did not start out with an original AMG 65 engine.

What I want to know is, is there any company or person who has taken a factory fresh CL or SL 65 and enlarged it's engine, or is planning to?

Treynor, if Renntech offered to enlarge your engine further for even more power and hopefully also have a tranny solution, would you consider it?

SL65amg

Still haven't got any answers on this yet ladies and gentlemen ....

hopefully somebody will know ...

The SL65 has an enlarged and reinforced SL600 engine, and the Brabus even more so

Id like to see it too, but i think the weight of the SL cars makes the tranny problem a bigger one than you think. I think the results would be better in the much lighter SLR, but modded like you want.

I know the old sl's r129 could have their v12's bored out to 7.4 by renntech, along ecu upgradeand lets say biturbos are good for 120hp + tranny upgrade you could be looking at an sl600 with 750hp, which would own the world... also I believe the upgrades were worth 60k total not sureso add that to the cost of buying the car, it would still be half the price of a brabus or renntech tuned sl65 amg, go figure how the older sl's have more power potential tahn newer ones...

Doctodd33

I think i disagree about a 750HP SL600 owning the world. A Porsche or Vette or Viper with 500HP would still outrun it cuz of the huge weight difference, and 500HP isnt hard to mod in a Porsche or Vette, and is already there in the Viper.

Yes, but what if for instance someone took a car like Shiznick's or Treynor's SL 65 's and modded the crap out of them, like enlarging the engine to over 7 liters, put in more powerful turbos and stronger tranny, then lightened the body with carbon fiber panels and, to level the playing field more fairly, took out all the hyrdraulic/electronic/servo/motors for the retractable hardtop, thereby making it essentially a dedicated hard top "CSL" type of SL.

You would have well over 800 or 900 horsepower, torque maybe 1,200-1,300+ lb/ft, and almost no street legal car in the world would be able to touch it after 80 MPH, not even an Enzo or a Koenigssegg CCR or a Carrera GT .... this new so-called SL 75 AMG GT-R would rule the streets as the designated king of the road, period. :v

I like the sound of that ... SL 75 AMG GT-R, a totally dedicated hard top very much lightened and upgraded version of an SL 65, I know AMG could build it in very small numbers as a top model above the SL 65 ..... now if they could also incorporate all-wheel drive and the all-wheel steering they've been working on with prototypes, and with a much wider set of tires than the SL 65 .... holy sh*t dude ..... no car could touch it ....

Damn, why can't AMG just build it? Then let all the auto magazines take it out onto the track and let's see what it'll do .....
Top speed 250+, zero to sixty in well under 3 seconds, quarter mile in 9, etc.. etc.. Now when they subtract the cost of all the luxury gizmos in the SL 65, which they are going to take out to save weight, from this new SL's price, and take out the cost of the retractable hardtop, etc.. ... the cost may actually be not too much over the cost of a standard SL 65, maybe $50,000 more ?

r129's weight is much less than the r230 as I am speaking of r129's the weight between those and vettes or vipers for that matter are not too far apart, coupled with the massive amounts of more hp and torque I would assume sl600's would win

Let it go.

You'd have to be a real baller to have the nerve to take apart a Mercedes V12 out of a 180+K car

Ashkan's C43

they did its called slr... or rather brabus slr

scorchie

What are you talking about? 2002 R129 SL600, 4455 lbs; 2005 R230 SL600, 4429 lbs.*

R129 weight "much less than" the R230? Doesn't look like it.

meant sl65 amg

Umm, still what are you talking about? 2005 R230 SL65, 4473lbs, which is 18 lbs heavier than an R129 SL600. Still less than 4 gallons of gasoline difference in weight. "Much less" doesn't seem to apply, I doubt that 18lbs is going to make any difference in performance on that heavy of a car, and the difference to a Viper or Vette is may hundreds of pounds.
